in all whom it may concern.-

Be it known that I, WESLEY M. SCOTT, a citizen of the United States, residing at Columand distributing the same to the axle or spindle upon which the wheel is mounted, to provide an improved construction of wheel-hub having receptacles or pockets for the reception of accumulated dirt or dust, and to produce other improvements, the details of construction of which will be more fully pointed out hereinafter. These objects I accomplish in the manner illustrated in'the accompanying drawings, in which- Figure l is an outer face view of my im- 7 Fig. 2 is a sectional view on line w a; thereof,-and Fig. 3 is an inner side view.

Similar numerals refer to similar throughout the several views.

1 represents the rim of a wheel, which in the drawings is shown in the form of a carwheel, although it will be obvious that my invention may be applied to wheels for other purposes.

2 represents suitable spokes, which radiate from a central hub or boxing 3. As indicated in the drawings, the body of the hub or boxing is provided with a central spindleopening 4, which is designed to receive the spindle 5 of an axle or shaft 5. The inner end of the hub 3 is extended beyond the body of the wheel and about the mouth of the opening 4 may be recessed to receive an axleshoulder 6. The forward side of the hub 3 parts is formed with a rim-like extension 7, the continuity of which is broken by an opening 8 therein, which is shown in Fig. -1. About the chamber 9 is through the medium of suitablyformed separated openings 11 made to communicate at diiferent points with the shaft or spindle bearing-opening 4. The forward side of the hub-body has formed therein an oilfeed opening which is closed by a suitable plug 12, this feed-opening being formed, as

ward extension 7 of the hub. In the forma tion of the hub-bod y 3 I provide at intervals rounded projections 13, the interiors of which communicate with the body of the oil-chamber and form oil-chamber recesses or pockets. Leading into each of these pockets is an internally-threaded opening, which is normally closed by the plug 14;

In utilizing my invention the desired quantity of oil is introduced through the oil-feed opening by the temporary removal of the plug 12, the oil thus supplied to the chamber 9 passing through the openings 11 to the surface of the spindle 4 and insuring the latter being oiled. In the revolution of the wheel it is obvious that any dirt or' foreign particles which might accumulate within the oilchamber will'through centrifugal motion of the hub be thrown outward and that the pockets or recesses 13 will serveto receive'and form a lodging-place for the dirt thus expelled. The dirt thus accumulated in. said pockets may be removed through the cleaneropenings, which are normally closed by the plugs 14. a

By providing the opening or break 8 in the tion of a cotter-pin 15 through the usual pinopening in the outer end of the spindle is permitted. It will be understood that the outwardly-projecting hub-rim 7 will serve as a hood for the end of the spindle and guard the latter against injury or breakage.

It will here be noted that the closure-plug 12 is located within theopening-S in the flange 7, with its outer end projected across the adjacent end of the pin or key 15, thereby preventing accidental displacement of the pin or key when the plug is in position, and hence this plug serves a double function.

From the construction herein shown and described it will be seen that not only is proindicated more clearly in Fig. 1 of the draw-. ings, between the separated ends of the forrim extension 7 it will be. seen that the inser-- through the inner side or end of the hub-body vided simple and efiective means for retaining and distributing the oil, but that improved means are provided in conjunction therewith for the collection and removal of dirt and foreign matter.

Having now fully described my invention, what I claim, and desire to secure by Letters Patent, is-

1. The combination with an axle-spindle having a diametric opening formed through the outer portion thereof, of a wheel rotatably mounted upon the spindle in rear of the opening therethrough and provided with an annular oil-chamber in communication with the spindle-receiving opening of the hub, the outer end of the hub being provided with an outwardly-directed substantially cylindrical flange projected in front of the adjacent end wall of the hub and having a portion omitted, a pin or key fitted to the opening in the spindle to prevent displacement of the hub, the outer end wall of the hub being provided with a filling-opening disposed between the opposite end portions of the flange and communieating with the oil-chamber, and a removable closure-plug fitted in said filling-opening and projecting externally of the adjacent end of the hub,'and forming an obstruction in the opening of the flange.

2. A wheel having its hub provided with an annular oil-chamber in communication with the spindle-receiving opening of the hub, there being a substantially cylindrical flange projected outwardly from the outer end of the hub and having a portion removed, the oil-chamber being provided with a plurality of radial outwardly-directed enlargements formingsediment-collecting pockets, the inner ends of which are provided with cleaningopenings formed through the inner end of the hub, one of the enlargements or pockets be ing located adjacent to and in alinement with the opening in the flange and provided in its front. end with a filling opening formed. through the front end of the hub and lying between the ends of the flange, and closure-plugs for the openings in the ends of the pockets.
